JOSEPH DISTER, 0F HAMILTON, OHIO, ASSIGNOR. TO AMERICAN CAN COMPANY, OFNEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

LARD-CAN.

Specification of Letters Patent.

Application filed October 4, 1916. Serial No. 123,622.

To all whom it may concern Be it known that I, JOSEPH DISTER, a citizenof the United States, residing in Ham ilton, in the county of Butler andState of Ohio, have invented a new and useful Improvement in Lard-Cans,of which the following is a specification.

This invention relates in general to containers and has more particularreference to containers of the character covered by Patent No. 1,073,859to Walden S. Laskey, granted Sept. 25, 1913.

The invention, however, has other and broader application as will beapparent as it is better understood.

A principal object of the invention is the provision of a cover for acontainer of the character described in said Letters Patent which willinsure the formation of a perfect closure and will materially aid inpreventing any deformation of the container body in looking the cover inplace.

In the patent mentioned it is contemplated to provide a wire in the edgeof the slip cover which may be drawn tightly about the container bodyafter the cover is in place to prevent its inadvertent removal and alsoto provide a tight seal for the container; a container having the coverso locked in place is adapted to be opened by severing the wire torelease the tension created about the flange of the cover.

Containers of this character are frequently 4 used for lard and othersubstances of such nature that the container should be kept closed afterit is first opened, these contamers bein large and used frequently forshipment in ulk. V

A further object of this invention is the provision of a containerclosure of this character which will provide an effective substantiallyhermetic closure after the wire has been cut and for use until thepackage or container is empty.

A further object of the invention is the provision of a slip coverhaving a flange adapted to extend down about the outside of thecontainer body and having also a plurality of friction walls enga firmlyand in metal to metal contact frlction walls correspondingly arranged onthe body.

Other objects and advantages of the in? vention will be apparent as itis better un derstood from the following description when considered inconnection with the accompanying drawin illustrating a preferredembodiment t ereof.

On the drawing,

Figure 1 is a side elevation of the container embodying my invention;

Fig. 2 is a large sectional view of the same; and

Fig. 3 is a top plan view on a somewhat reduced scale.

For the purpose of illustrating my invention I have shown on the drawinga oontainer body 3 having depressions 6 near its upper edge andterminating in the reinforced edge 4 formed by curling over theextremity 5 of the body. The curled over edge 4 is preferably ofrelatively large diameter. The cover 7 is depressed near its edge and atits center 8 is somewhat domed to permit yielding about the connection11 with the portion of the cover beyond the center. This portion extendsupwardly from the depressed part 11 to form a friction wall 10 and isbent therebeyond in a curve 12 and downwardly, forming a friction wall9. The lower edge of the wall or flange 9 is provided with a pluralityof spaced lips 13 in which the locking wire 14 is held, these lips beingbent up around the wire as indicated in Figs. 2 and 3. The wire 14 has aloop 15 which may be compressed, as indicated in dotted lines, to lockthe cover in place. This draws the wire tightly about the body of thecontainer, which is of relatively yielding material.

The friction walls 9 and 10 embrace the curled edge 4 which formsfriction walls in engagement with the friction walls 9 and 10" the coverat erably made of thin sheet metal to be read- L ily yieldable. Thecover portions disposed about the wire constitute curved flangesembracing it and the spacing of these flanges tight closure to preventcontamination of the contents between the times when the cover isremoved to provide access to the interior.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparentthat various changes may be made in the form, construction andarrangement of the parts without depart ng from the spirit and scope ofthe invention or sacrificing any of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

1 claim:

. 1. in a slip cover can, the combination with a sheet metal can'bodyhavingfian external locking shoulder, of a slip cover havmg a dependingflange furnished with an internal locking shoulder adapted'to engage theexternal locking shoulder on the can body and a contractible wire bandprovided with a loop and surrounding the flange of the slip cover andcontained within a curled portion of the flange, said flange of the sl1pcover having a notch therein for said loop to project through, saidcover having an internal frictional engagement with the top of saidbody, substantially as specified.

- 2. in a slip cover can, the combination with a sheet metal can bodyhaving an external locking shoulder, of a slip cover having a dependingflange furnished with a locking shoulder adapted to engage the externallocking shoulder on the can and a contractible, stifl, bendable bandsurrounding the flange of the slip cover, said band having an integrallyformed contractible loop therein, the members of which are adapted to bepinched together to tighten the band, said can body being adapted to becontracted when the loop is pinched together and to ewand and take upthe slack in the band after the loop has been formed, and said coverhaving an internal engagement within said body to prevent unduecontraction of said body.

3. In "a slip cover can, the combination with a sheet metal can bodyhaving an external locking shoulder, of a slip cover having a dependingflange furnished with an internal locking shoulder adapted to engage theexternal locking shoulder on the can body, and a contractible wire bandhaving a contractible loop and surrounding the flange of the slip cover,said depending flange of the cover having a curled flange or portionadapted to retain the wire band in place, and said cover having africtional engagement within said body.

4:. In a slip cover can, the combination with a thin sheet metal canbody, of a thin sheet metal lip cover, having a thin sheet metaldepending flange embracing the up per end of said body and acontractiblemetal band encircling the fl'ange of the cover, and having an integralcontractible loop therein, said loop being adapted to lock and tightenthe band on said body causing it to produce a tight closure therewithwhen the loop is pinched together, and said cover having a portiondisposed within the body and in frictional engagement with its upperopen I end.

5. In a slip cover can, the combination with a sheet metal can bodyhaving an external locking shoulder, of a slip cover having a dependingflange furnished with an internal locking shoulder adapted to engage theexternal locking shoulder on the can body, and a continuous and endlesscontractible wire band having an integral contract ible loop andsurrounding the flange of the slip cover, said depending flange of thecover having a curved flange adapted to retain the Wire band in place,said curved flange having openings whereby the same is adapted to easilybend when the wire band is contracted, and said cover having a partdisposed within the upper open end of said body and in engagementtherewith.

6. In a cover sealing means for sheet metal cans, the combination with acan having an external locking shoulder near the top edge of the bodyportion, of a sheet metal slip cover having a depending metal flangeprovided with a curved portion, a con tractible band formed with anintegral compressible and severable loop projecting from the coverflange and so pinched that when the cover is placed on the can and thepro-' ecting loop is compressed the wire band is caused to contractwhereby the cover flange is resiliently held in looking engagement withthe external locking shoulder of the can and whereby when the encirclingband is severed the restrained resilience of the can body and coverflange is released thereby pennitt'ing easy removal of the slip cover,and said cover having a part disposed within the upper edge of said bodyportion in engagement therewith.

In a slip cover can, the combination of a can body of a slid coverhaving a contractible wire about the edge of its embracing flange andbeing depremed near its edge to be disposed within said body when thecover is pos1tioned, sai-d' depressed part forming an abutment torestrain contraction of the body when said wire is contracted.

8. In a slip cover can, the combination of a body having a curled edgeat its. top, a slip cover havingopposing substantially Vertical frictionWalls engaging said edge on 0pposite sides and having a contractibleband at :the edge of its body embracing flange, contraction of said bandserving to lock said cover in place, and said friction walls serving toreinforce the can when said wire is contracted, and to form a hermeticclosure when said wire is unconltracted.
